Pulp & Paper

Speed, precision and control are critical in the fast-paced pulp and paper industry. Northstar offers a wide range of heavy-duty encoders and mill-duty magneto-resistive encoders designed to meet the performance and environmental extremes of the pulp and paper mills industry including Northstar brand RIM Tach® Series encoders.

Our comprehensive line of digital control systems provides reliable speed and web tensioning control for reliable plant operation. These rugged, standardized and customized digital encoders are engineered with magneto-resistive technology to track machine speed for precise control in the harshest of environments.

Our Mill-Duty (RIM Tach®) encoders provide reliability and precision even under the most challenging conditions and provide solid signals to precisely track machine speed for better control and for trouble-free and trustworthy performance. Our Heavy-Duty (Slim Tach®) encoders incorporate a bearingless and ultra-thin design for longer encoder life and a variety of motor mounting possibilities.

HSD37 Harsh Duty Optical Encoder

Paper mills require equipment that is robust enough to handle dust and moisture while performing time critical applications. The HSD37 harsh duty optical encoder is built with an unbreakable plastic or stainless steel code disc, and is environmentally sealed at both ends preventing the penetration of dirt and moisture.

RIM Tach®8500 NexGen

The NEW RIM Tach®8500 NexGen was designed with the customer in mind. Now with the largest air gap (70 thousandths) in the industry the NexGen RIM Tach provides more generous axial play allowing for easier installation. To learn more about this revolutionary encoder click on the image above.

HS60

With an industry leading 2-7/8” hollowshaft capability, the HS60 fits large motor shafts in pulp and paper mills. Oversized bearings, multi stage sealing and stainless steel construction all add up to an encoder that is resistant to moisture and contamination.
